Been listening to this almost as much as Bad Apple. Almost. 
The music for this game is pretty calming, almost soothing actually. It’s a mix between World Ends with You at some points, throw in some tarot cards and a Japanese school with Final Fantasy turn based system and there you have Persona 3 for the PS2. Well, that’s how I interpreted it!!! XDD
I’m loving the gameplay, the story’s quite good too! I can’t wait till the next full moon in the story, a lot of stuff seems to go down on the night of the full moon….

The music here is the final battle music for the game, where you go up against a person/monster/thing called Nyx. I’ve seen countless pictures of him and have fallen completely in love with his character design! I’m only 1/3 of the way through the game (I think, I haven’t looked up any walkthroughs yet!) and I am TOTALLY PSYCHED TO FACE NYX!!!!

Also, this version goes for 10 minutes. So technically, I might have listened to it just as many times as I have for Bad Apple……
